FIELD OF THE INVENTION

This invention is in the field of car accessories or other fields wherethere is a need for air under pressure and more specifically arefillable container of pressurized air.

BACKGROUND OF THE INVENTION

Vehicle tire emergency equipment is known in the art and usually takesthe form of pressurized cans with a substance inside that is capable ofstopping up relatively small holes in the tire. When such cans areapplied to punctured tires, the pressurized air in the can blows airinto the tire and the said substance does its job of repairing, oftenonly temporarily, the hole that caused the puncture. The disadvantage ofsuch cans is that the tire repair substance is said to damage tires orcause instability to the wheel and should be removed as soon aspossible. Such removal is a messy and time consuming work.

Another disadvantage is that car owners do not always want to injectrepair fluids into the tire for example if the tire is missing a smallamount of air and needs just a top-up. Another disadvantage of the cansis that they are one time disposable items resulting in a costly productif they are needed any more than infrequently.

This invention reveals a method of inserting air into tires or any otheritems that need air under pressure inserted in them where the containercontaining the air can be re-filled.

SUMMARY OF THE INVENTION

It is to be understood that both the foregoing general description andthe following detailed description present embodiments of the inventionand are intended to provide an overview or framework for understandingthe nature and character of the invention as it is claimed. Theaccompanying drawings are included to provide a further understanding ofthe invention and are incorporated into and constitute a part of thisspecification. The drawings illustrate various embodiments of theinvention and, together with the description, serve to explain theprinciples and operations of the invention.

This invention reveals a container or other kind of vessel that iscapable of withstanding high pressure gas inside. The container wouldhave a one-way valve for inserting air under pressure and a differentone-way valve for allowing air to exit into the object desired to befilled. The said two kinds of valves would have external attachments oradapters to facilitate connection to air pressure apparatus and car tirevalve fitments respectively. There could be further adaptors to enablethe container to attach to other items like, for example, an inflatablemattress, an inflatable boat, a football or an outdoor grill to fan theflames of the smoldering coals. There could be a handle with a squeezetrigger or button to release the out-going air in a controlled manner.There could be safety device like a removable pin across the movementradius of the trigger to prevent accidental release of air. A releasebutton could have an on/off switch to prevent accidental release of air.

The filling and re-filling of the container of air could be at any placethat has a source of high air pressure and a connection to suit theadaptor of the inflow air of the container. Examples of such places aregas stations that have tire filling machines or workshops that have aircompressor machines. These air compressor machines could be adjusted toa pressure much higher than needed in the tire so that the containerwould be filled with air at this higher pressure.

The container would be so filled with air at high pressure and whendesired, the air would be released into a tire or other inflatableobject where the pressure would be less because the volume of thereceiving vessel is usually greater than that of the pressurizedcontainer.

There could be a pressure gauge on the input valve to measure thepressure of air entering the container and a pressure gauge on theoutput valve to measure the pressure of the air in the tire or othervessel.

There could be a pressure gauge on the container that would indicate thepressure in the container at all times. In addition or alternativelythere could be a scale to indicate what starting pressure is necessaryto fill a car tire to a given pressure. For example, a user has a carwhose tires need 28 pounds per square inch of pressure and the scalewould indicate that he would need to fill the container with air to apressure of 90 psi. in order to reach 28 psi. in the tire.

Alternatively, there could be a control valve on the container thatcould be set to 28 psi. and it would let out the appropriate amount ofair.

There could be safety features like childproof operating handles assometimes seen on fire fighting sprays to prevent accidents and childrenplaying games with the pressured air.

The air pressure gauges could be mechanical or digital. The highpressure container could be attached to the wheel of a vehicle or builtinto inflatable vessels like an inflatable boat or inflatable swimmingpool. This feature to attach or build-in would serve to store thecontainer in a safe and known place when not in use and be readilyavailable when needed.

The high pressure container could be made to a size and shape suitablefor attaching to bicycles and being a volume suitable for bicycle tiresand made to handle air pressure suitable for bicycle tires.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings, which are incorporated in and form a part ofthis specification, illustrate embodiments of the invention and togetherwith the description, serve to explain by way of example only, theprinciples of the invention:

FIG. 1 is a schematic depiction of a reusable container used for fillingwith air under pressure and releasing air into target items.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As will be appreciated the present invention is capable of other anddifferent embodiments than those discussed above and described in moredetail below, and its several details are capable of modifications invarious aspects, all without departing from the spirit of the invention.

Accordingly, the drawings and description of the embodiments set forthbelow are to be regarded as illustrative in nature and not restrictive.

FIG. 1 shows a container 100 used for filling with air under pressure.The connector 102 has in it a one way valve to let air in but not letair out. At the extremity of the connector 102 is an adaptor 104 made tofit the chosen method of filling the container 100 with air. This couldbe exchanged when alternative sources of air pressure require differentadaptors. There is a carrying handle 101.

The connector 106 is for attaching to objects that require filling withair for example tires of vehicles. The connector 106 would have anadaptor to suit the connection piece of the object receiving the air, inabove example, the valve of a vehicle tire. The connector 106 would havea one way valve that would allow the air to exit from container 100 whena piece protruding from the receiving object pushes in the valve control110 being a small rod at the entrance to the valve of connector 106 thatwould need to be pushed in to open the said valve to allow air flow fromthe container 100 into the object being filled with air. A tube with theappropriate fittings could be used to aid making the connection betweenthe exit connector 106 and the item requiring inflation.

There could be a number of air pressure gauges on the container 100 toindicate the air pressure at different places. One gauge 112 could beattached to the air entrance connector 102 to measure the incoming airpressure. Another gauge 114 could be attached to the air exit connector106 to measure the out-going air pressure and the pressure in the itemthat has had air inserted in it. Another gauge 116 could show the airpressure in the container 100 at any given time. There could be asliding scale 118 attached to the container 100 that could assist usersto fill the correct amount of air pressure to fill their object forexample a tire, to the correct pressure without relying on gauges. Thescale 118 could show for example, in order to fill a tire to 28 psi.,fill the container to 90 psi. and so on. Then a user could go to a gasstation or other source of compressed air and adjust the air compressorgauge to 90 psi., attach the connector 102 and fill to capacity. Hewould then empty all the air in that container 100 into the tire byconnecting the connector 106 to his tire. The result would be that thetire would be at approximately 28 psi.
